Finally, I found a European supplier of Fujifilm TY, Damrotech. After a bit of research, I found out it's actually the same guys that were XCITEK (at least one of them).
25pcs of Fujifilm TY DVD+R costs â‚¬9,90 ($12,50)
eBay (Auction ends 15 04 05, after that, click here)
Shipping costs are ok, but you might want to compare it to Opusshop or gÃ¼nstig-brennen.
